What causes the greatest level of stress for drivers? According to Tom Vanderbelt, author of Traffic, Why We Drive the Way We Do (and What It Says About Us), the greatest stress for drivers comes when they have to merge. Yield signs. which assign the right of way at intersections where a stop is not required, and alert drivers to the need to merge into a shared driving path. Yield Traffic Signs call for a collaborative process between drivers. But many studies have shown that drivers are often more intent on competition than on cooperation. The result can be potentially dangerous behavior, sometimes causing crashes, and guaranteed to create a whole lot of stress.
The first Yield traffic signs were developed in 1934 by Clinton Riggs, a Tulsa police officer, who used a 5-sided "keystone" shape and black legend on yellow background. When added to the Manual on Uniform Traffic Control Devices in 1954, the yield sign was standardized as a point-down equilateral triangle. But it was still a yellow yield sign. Not until 1971 was the Yellow Yield Sign replaced by the Red Yield Sign, with its red text on a white field that we know today.
If you need to buy yield signs for mounting on private property, such as in a parking area or on private roads, keep in mind that even though signs on private property and roads are not regulated by government, it just makes sense to use the same signs all drivers instantly recognize and respond to. Like our STOP signs and other road signs, the Yield Signs we make at STOP Signs And More meet MUTCD sign regulations. These are the same high-quality reflective Yield Signs we make for local, state and federal agencies for use on public roads.
To make a great Yield Traffic Sign, you have to start with excellent materials. We use 5052-H38 sheet aluminum in .063 or .080 gauges pre-treated in accordance to ASTM Designation B 449. The surface of the sheet aluminum is cleaned, deoxidized, and coated with a light and tightly adherent chromate conversion coating free of powdery residue. We use only Federal Highway Administration fonts for the lettering on our Yield Signs, and we silkscreen print with 3M outdoor transparent inks onto 3M Engineer Grade Prismatic or 3M High Intensity Prismatic retro-reflective sheeting. When you buy Yield signs that are High Intensity Prismatic they carry a warranty from 3M for a minimum of 10-years without appreciable fading. Your Yield Traffic Sign can last even longer when you have us add 3M 1150 protective overlay laminate film (POF) to the face of the Sign. POF not only gives the Yield sign added protection from harsh weather and sunlight, but acts as a graffiti barrier. If the sign is tagged with graffiti, you can use a mild detergent like Simple Green to easily wash the vandalism away. That saves the cost of having to buy and mount a new sign.
